There are many “deaths” involved in following Christ, however obscured they may be in today’s cushy forms of Christianity. The following are five likely losses that come with truly embracing the cross of Christ.

"The coast is beautiful" is something existentially true and intuitively felt among all humans. We are drawn to the places where land meets sea, where water meets rock; two very different things, coming together, producing an aesthetic pleasure and a life-giving good. We are attracted to this because it is a familiar cosmic reality.

"The heavens declare the glory of God, and the sky above proclaims his handiwork" (Psalm 19:1). The heavens declare. The stars speak. They bear witness to the glory of God. But what do they say? Our gaze is naturally drawn upward. We are curious about what's up there. Beyond us. Both discoverable and undiscoverable. Our frontier longing beckons us to the telescope. To search the vast heavens. To know what we can know, but maybe moreso to know what we cannot know.

I’m a theologically conservative evangelical Christian who is ardently pro-life, pro-family, pro-traditional marriage. I’m also ardently pro-environment. All of these positions are connected and stem from my faith more than my politics, particularly a glad acceptance of and respect for God’s created order. Here are my arguments for why care for the environment should be a concern for conservative Christians.

I've been thinking a lot about the Lord's Supper recently, and why I find it increasingly crucial and comforting amidst the manifold discomforts of 21st century life. It has struck me that the Lord's Supper is a bit like time-travel. The weekly eucharistic ritual, enacted by millions of Christians every Sunday, transports us simultaneously to the past, present and future. And each of these modes is beautiful and nourishing.

I sometimes imagine that in heaven, one of the joys of living in eternity will be that we'll have the ability to re-live the best days and best memories from our earthly lives. But I know that in heaven, all these transient things (such as 24-hour periods we once called "days") will be quaint memories compared to the "eternal weight of glory beyond all comparison" we will be experiencing.

What does it mean that when Jesus entered Jerusalem the week he was crucified, the crowd "took branches of palm trees" (John 12:13) to welcome him? What do we make of the moment when Jesus curses the fig tree? What does it mean that the Bible begins with a “Tree of Life" in Eden (Gen. 2:9) and ends with a "Tree of Life" at the end, a tree whose leaves "were for the healing of the nations" (Rev. 22:2, 14, 19)?

The long-gestating epistemological crisis in the west is escalating rapidly. Who or what can be trusted? Is objectivity possible? Are there authorities uncorrupted by power? Sources of truth untainted by the stains of bias and ideology?

The following 21 challenges are in no particular order and are by no means exhaustive, and they are largely (but not exclusively) reflective of an American evangelical context. I also should note that each of them represents not only a challenge but also an opportunity. The church has historically thrived when she is tested rather than comfortable.

This week Donald Trump, Jr. tweeted a photo of an ad that compared the “Syrian Refugee Problem” to a bowl of Skittles. The ad suggested that we can best understand the worst humanitarian crisis of our time by thinking about refugees not as embodied, suffering people but as poisonous rainbow-colored candy that could kill us. Let’s set aside for a minute the politics of this and the admitted complexity of immigration and national security.

It was 15 years ago this month that I was a college freshman at Wheaton College. I still remember that August: packing up my parents’ car and driving from Kansas City to the Chicago suburbs, shopping at Target for dorm room necessities, attending orientation week activities, meeting people for the first time who would become my best friends. In many ways those days were the turning point in my life, the beginning of my intellectual and spiritual coming of age.

The word “gospel” is a noun and an adjective and a verb and an industry that has become as amorphous as the word “evangelical.” I often hear about how this or that is a “gospel” issue, or how the litmus test of a good church is whether or not they are “gospel-centered.” Blogs and coalitions and conferences and genres of music claim the name.

Writing to a group of early Christians in Corinth, the Apostle Paul famously said, “the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God” (1 Cor. 1:18). Christ crucified was “a stumbling block to Jews and folly to Gentiles” (v. 23), a foolish thing and a sign of weakness. In the ancient world a cross was not something decorative to put atop buildings or wear, diamond-studded, around one’s neck. It was a barbaric method of slow death.

I’m sitting here looking at the Christmas tree in our room, a 7-foot Noble Fir, still aromatic and alive, glistening with lights and glittery ornaments. Part forest and part carnival, a natural and cultural creation, it stands as a shy but stately symbol of so much more than just holiday cheer. Its triangular, evergreen shape and prickly, shedding branches tell a much bigger story.

At this week’s “Future of the Church” discussion at Biola University (well worth watching online in its entirety here), the brilliant Fred Sanders ended his prepared remarks by suggesting that it may be up to the “children of evangelicalism” to make progress in the dialogue of unity/ecumenism. Such a project is perennially attempted but always met with the same pesky roadblocks (the “essentials versus non-essentials” conversation being unavoidably amorphous, given the decentralized DNA of Protestantism).

In the Christianity of my Midwestern Baptist upbringing, the Holy Spirit was a part of the Trinity I acknowledged but hardly understood. I recall hearing murmurs that one of my classmates in third grade was a “charismatic,” which meant they were just as misled as the one Catholic family on our block. When we visited churches where people raised hands in worship, we assumed they were liberal or in some other way cooky. In junior high I remember hearing my sister describe the trauma of attending a charismatic church service with a friend. There were healings and speaking in tongues. The horror! In our minds this was essentially a cult.

If you've grown up in America--or even if you've just had America imported to you via media and pop culture--the air you breathe with respect to identity and purpose is something along the lines of "be who you want to be," "follow your dreams," "find yourself," "don't let anyone get in the way of your dreams."

When I think about the times in my own Christian life when I felt the Spirit of God most powerfully, loved the Bride of Christ most profoundly and glimpsed the "city yet to come" most clearly, I recall most readily the moments where I worshipped and fellowshipped alongside believers who were very different from me and yet were clearly family.

The "Future of Protestantism" event gathered Peter Leithart, Fred Sanders and Carl Trueman together on one stage to debate exactly what the event's title ponders: what form should Protestantism take going forward? Is the "protest" of the Reformation still necessary or should unity as the one body of Christ be the goal as religion in general becomes marginalized in the secularizing west? Leithart's perspective is that Protestantism, insofar as it is defined in opposition to Catholicism (or Eastern Orthodoxy), should end. It's time for unity, he argues; unity is internal to the gospel itself.
